Automatically correcting touchscreen errors

ABSTRACT

Provided are techniques for automatically correcting touchscreen errors. A first location input is received from a user touching a global touchscreen of a global device, where the first location input is a location relative to a display surface of the global touchscreen. It is determined that movement of the global device is different from movement of a local device. Motion information of the local device is retrieved. The first location input is corrected to a second location input based on the motion information. In response to the second location input, an operation is performed.

BACKGROUND

Embodiments of the invention relate to automatically correcting touchscreen errors. In particular, embodiments of the invention relate to automatically correcting touchscreen errors of a device through external or non-worn sources of information.

There are strategies and systems to detect and correct wrong typing when using a touchscreen of a device. Some strategies are based on human behavior and general interaction with the touchscreen, especially its keyboard, while other strategies are based on motion sensors (e.g., accelerometers).

These strategies are useful in detecting situational impairments by leveraging the motion sensor inside the device that is exposing the touchscreen. These strategies are based on the assumption that the relative movement of the finger and the touchscreen is the same, so that errors caused by walking vibrations and/or loss of attention may be corrected by the inner motion sensor of the device.

For example, a person is holding a smartphone with a touchscreen and walking. The motion sensor inside the smartphone measures the acceleration of the person based on the assumption that the smartphone and the person are one unique rigid body. Therefore, the inertia causing a relative delta movement of the finger on the touchscreen is proportional to the acceleration measured by the motion sensor of the smartphone.

DETAILED DESCRIPTION

The descriptions of the various embodiments of the present invention have been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.

Embodiments automatically correct errors in typing on a touchscreen of a device that does not have a motion sensor (e.g., an accelerometer) or where the inner motion sensor of the device cannot be put in a direct relationship with the movement of the user. For example, embodiments automatically correct touchscreen errors in the following scenarios:

-   -   the touchscreen and the user using the touchscreen are not one         rigid body, therefore, the relative movement of the finger of         the user and the touchscreen are not the same;     -   the device does not have an installed motion sensor; and     -   more than one user may use the same touchscreen simultaneously.

FIG. 1 illustrates, in a block diagram, a computing environment in accordance with certain embodiments. A vehicle 100 includes a global device 110 and one or more local devices 150 a . . . 150 n. The vehicle 100 may be a car, an electric bicycle, an airplane, a truck, a motorcycle, etc. For example, the global device 110 may be a device that is part of a car's console or may be a device on a seatback of an airplane. The global device 110 may be described as an external or non-worn device (e.g., the global device 110 is not worn by a user (i.e., a person)).

The global device 110 may be a device integrated with the vehicle, and the global touchscreen 122 may be used to select various services (e.g., navigation, music, phone calls, etc.). The global device 110 is coupled to or includes a data store 140. The global device 110 includes a global correction engine 120, a global touchscreen 122, and may optionally include a global motion sensor 124. Thus, in some embodiments, the global device 110 includes a global motion sensor 124, and, in other embodiments, the global device 110 does not include a global motion sensor 124. The global touchscreen 122 may be an interactive keyboard or other user interface.

Each local device 150 a . . . 150 n may be a smartphone, a wearable device (e.g., a smart watch), a tablet computer, a laptop computer, or any other device with a touchscreen. Each local device 150 a . . . 150 n includes a local correction engine 160 a . . . 160 n, a local touchscreen 162 a . . . 162 n, a local motion sensor 164 a . . . 164 n, and local device and user information 166 a . . . 166 n. The local device and user information 166 a . . . 166 n includes one or more attributes about the local device 150 a . . . 150 n and one or more attributes about each user who uses the local device 150 a . . . 150 n and provided a user mark. The local device information includes a local device identifier that identifies the local device 150 a . . . 150 n and may include other attributes about the local device 150 a . . . 150 n (e.g., type of device (smartphone or smart watch), brand of device, etc.). The user information for a user includes a user identifier (e.g., a user name), a user mark (e.g., a fingerprint, a word, a symbol, etc.) and may include other attributes about the user.

The data store 140 includes local device and user information 142 a . . . 142 n that corresponds to the local device and user information 166 a . . . 166 n. When the global correction engine 120 receives the user mark, the global correction engine 120 uses the local device and user information 142 a . . . 142 n to locate the user mark, identify the user who provided the user mark, and identify the local device 150 a . . . 150 n of that user. In certain embodiments, the data store 140 includes local device and user information 142 a . . . 142 n for a subset of the local devices 150 a . . . 150 n (e.g., because one or more local devices 150 a . . . 150 n have settings so that they do not communicate with the global device 110.

In certain embodiments, each motion sensor 124, 164 a . . . 164 n is an accelerometer. In certain embodiments, any motion sensor 124, 164 a . . . 164 n that provides motion (e.g., acceleration) of the device or that may be used to calculate motion (e.g., acceleration) of the device may be used.

The global correction engine 120 communicates with a local correction engine 150 a . . . 150 n to adjust a location input (e.g., a position) on the global touchscreen 122. For example, if a user in a car intends to place a finger on position X50,Y20 on the global touchscreen 122 to select a “call” button, but, due to movement of the car, the finger is inadvertently placed on position X40,Y15, then the global correction engine 120 identifies the correct position of X50, Y20 as location input to the global touchscreen 122 and, in some embodiments, notifies the local correction engine 160 a . . . 160 n to accept input of X50,Y20 when the local correction engine 160 a . . . 160 n is to perform some processing based on the location input. In particular, the global correction engine 120 leverages the local motion sensor 164 a . . . 164 n of the local device 150 a . . . 150 n to make the correction.

With embodiments, the global correction engine 120 corrects errors made by a driver of a car (i.e., a type of vehicle 100) while typing on the global touchscreen 122, where the errors occur because of sudden shocks transmitted to the driver as the car's motion is impacted by bumps, road conditions, braking, vibrations, etc. With embodiments, the global correction engine 120 corrects errors made by a passenger of an airplane (i.e., a type of vehicle 100) using a global touchscreen 122 during turbulence. In these examples, conventional solutions that rely on accelerometers (a type of motion sensors) do not work because the touchscreen installed in cars or airplanes typically do not have accelerometers.

Even if accelerometers are installed in the cars or airplanes with the global touchscreens 122, the passenger/driver and the global touchscreen 122 are not a unique rigid body. Instead, dampers or shock absorbers installed in the seat (of the car or airplane) or in the vehicle create a more complex physical condition where the global touchscreen 122 is not held by the user who may be moving, which means that the user and the global touchscreen 122 are not a unique rigid body.

Although examples herein may refer to a car, embodiments also apply to other vehicles (e.g., an airplane).

FIG. 2 illustrates devices in a car in accordance with certain embodiments. In FIG. 2, a car 200 includes a global device 210 (i.e., a vehicle device) with a global correction engine 212 and a global touchscreen 214. The car also includes two smartphones 230, 240 (i.e., local devices). The driver (one user) has one smartphone 230 with a local correction engine 232 and a local motion sensor 234, and a passenger (another user) has another smartphone 240 with a local correction engine 242 and a local motion sensor 234.

If the car 200 has a shock (e.g., due to a bump in the road, road conditions, braking, vibrations, etc.), the relative movement of the global touchscreen 214 installed on the car's console is different from the movement of each user (because of many factors, such as seats absorbing part of the shock, distance from the global touchscreen 214, the user's attributes, etc.). This leads to errors in the user touching the global touchscreen 214 that are proportional to the difference of the motion (e.g., acceleration) of the global touchscreen 214 and the motion (e.g., acceleration) of the user. In this example, the user and the global touchscreen 214 are not a unique rigid body, and this makes ineffective the (potential) usage of any motion sensor (e.g., accelerometer) present in the car 200.

Assuming the user and smartphone 230 or 240 form one rigid body, the error is proportional to the difference in motion (e.g., acceleration) of the two objects: the global touchscreen 214 (object 1) versus the smartphone 230, 240 (object 2). With embodiments, the global correction engine 212 of the vehicle device is able to communicate with the local correction engine 232, 242 of the smartphone 230, 240 to obtain the motion of the smartphone 230, 240 from the local motion sensor 234, 244. Then, the global correction engine 212 adjusts the location input of the user's finger on the global touchscreen 214 based on the real motion of the smartphone 230, 240 of the user (where the user's finger is designated as moving the same as the smartphone 230, 240).

FIG. 3 illustrates motion (e.g., acceleration) of devices in the car in accordance with certain embodiments. In FIG. 3, a user has a smartphone 230 and is using the global touchscreen 214. When there is a bump in the road as the car 200 is moving, the user's seat causes the user to have a longer vertical movement 310 to better absorb the bump. However, the global touchscreen 214 follows the car's movement and has a shorter vertical movement 320. The user's finger movement is measured by the motion sensor on the user's smartphone 230 as Dp′ 300. The global touchscreen 214 uses the measurement from the motion sensor of the smartphone 230 (Dp′) as input and corrects the location input of the user's finger on the global touchscreen 214.

FIG. 4 illustrates a global device and local devices in accordance with certain embodiments. A global device 400 is coupled to a database 410 (i.e., a type of data store) for storing local device information and user information. In certain embodiments, the global correction engine of the global device 100 is a plugin. The global device 400 also recognizes and is able to communicate with local devices 420, 430, 440. The global device 400 has a global touchscreen 400 with a display surface 404. The global correction engine of the global device 400 receives sensor input data from a touch sensor of the global touchscreen 402 that indicates location information relative to a display surface 404 of the touchscreen 402.

Initially, the global correction engine of the global device 100 discovers and registers the local devices 420, 430, 440. The global correction engine of the global device 100 also associates the local devices with users based on user marks (e.g., fingerprints, words, symbols, etc.) provided on the local touchscreens of the local devices 420, 430, 440. Then, the global correction engine of the global device 100 applies a correction factor to movement of a finger on the global touchscreen based on movement determined by a motion sensor of the local device 420, 430, 440.

FIG. 5 illustrates, in a flowchart, operations for device registration in accordance with certain embodiments. Control begins at block 500 with the global correction engine 120 of the global device 110 communicating with each local correction engine 160 a . . . 160 n of each local device 150 a . . . 150 n in the vehicle 100 to request local device information 142. In certain embodiments, the device information is a device identifier. In other embodiments, other device information may be provided, such as a protocol for communicating.

In block 502, the local correction engine 160 a . . . 160 n of each local device 150 a . . . 150 n in the vehicle sends the local device and user information 142 a . . . 142 n to the global correction engine 120. In block 504, the global correction engine 120 receives the local device and user information 142 a . . . 142 n from each local correction engine 160 a . . . 160 n. In block 506, the global correction engine 120 stores the local device and user information 142 a . . . 142 n in the data store 140.

Thus, the processing of FIG. 5 allows for coupling the global device 110 and each local device 150 a . . . 150 n. With various embodiments, identification of devices for coupling them and exchanging information may occur in different ways.

FIGS. 6A, 6B, and 6C illustrate registration, monitoring, and correction in accordance with certain embodiments. Control begins at block 600 with the global correction engine 120 receiving a first location input from a user touching a global touchscreen 122 of a global device 110 of a moving vehicle 100, where the location input is a location relative to a display surface of the global touchscreen 122 and indicates a user mark. That is, in certain embodiments, a user uses a finger to provide a user mark, such as a fingerprint, at the location of the first location input. The processing of block 600 may be described as receiving sensor input data from a touch sensor of the global touchscreen 122, where the sensor input data provides the location input relative to a display surface of the touchscreen.

In block 602, the global correction engine 120 determines whether the user mark for the user is stored in a data store 140. If so, processing continues to block 604, otherwise, processing continues to block 620 (FIG. 6C).

In block 604, the global correction engine 120 retrieves, from the data store 140, local device and user information 142 a . . . 142 n associated with the user mark to identify the local device 150 a . . . 150 n for that user. In certain embodiments, the user mark is a fingerprint, and the global correction engine 120 receives the fingerprint of the user and uses the fingerprint of the user to identify the local device 150 a . . . 150 n. In certain embodiments, multiple users may access the same global touchscreen 122, so the local device and user information 142 a . . . 142 n retrieved is particular to the user whose user mark has been received.

In block 606, based on monitoring, the global correction engine 120 determines that movement of the global device 110 is different from movement of the local device 150 a . . . 150 n. In block 608, global correction engine 120 determines whether there is a need to adjust the first location input based on the movement. If so, processing continues to block 610 (FIG. 6B), otherwise, processing continues to block 600 (FIG. 6A).

When determining whether to correct the error, the global correction engine 120 takes into account whether the local device 150 a . . . 150 n providing the motion information is one rigid body with the user. Sometimes the local device 150 a . . . 150 n is not a rigid body with the user. For example, this may happen if the local device 150 a . . . 150 n is on a bag or on a vehicle's shelf (in which case the local device 150 a . . . 150 n is one rigid body with the vehicle and, thus, with the global touchscreen 122). As another example, this may happen if the user is moving the local device 150 a . . . 150 n (e.g., with one hand, while using the local device 150 a . . . 150 n with the other hand). Therefore, the global correction engine 120 determines whether or not to apply a correction factor. In the case in which the local device 150 a . . . 150 n is one rigid body with the global touchscreen 122, the correction factor may be zero or near zero, which results in no or a small correction being applied. In the case in which the local device 150 a . . . 150 n is moving, the correction factor may be either high or fluctuating in a short timeframe, which may be two conditions checked by the global correction engine 120 to decide whether or not to perform the correction.

In block 610, the global correction engine 120 requests motion information (e.g., acceleration information) from the local correction engine 160 a . . . 160 n of the local device 150 a . . . 150 n. This indicates movement of the user associated with the local device 150 a . . . 150 n. In block 612, the local correction engine 160 a . . . 160 n of the local device 150 a . . . 150 n obtains the motion information from the local motion sensor 164 a . . . 164 n sends the motion information to the global correction engine 120. The In block 614, the global correction engine 120 receives the motion information. This may be described as receiving motion information from a motion sensor 164 a . . . 164 n of the local device 162 a . . . 162 n.

In block 616, the global correction engine 120 corrects the first location input to a second location input to be used as input to the global touchscreen based on the motion information. For example, if the user put a finger on the global touchscreen 122 as the car went over a bump, then the user has a different motion than the global touchscreen 122, and the user's finger lands in a different location on the display surface of the global touchscreen 122 than desired by the user (e.g., on an “end call” button on the global touchscreen 122). To correct this, the global correction engine 120 takes the motion information of the user into account to determine a second location input on the display surface of the global touchscreen 122 that is deemed to be the desired location on the global touchscreen 122 (e.g., on a “mute” button on the global touchscreen 122). In block 618, in response to the second location input, the global device 110 performs an operation (e.g., the second location input selects a “mute” button, and the global device 110 performs a mute function). Thus, with the correction of the first location input to the second location input, in this example, the global device 110 process selection of a “mute” button instead of selection of an “end call” button. From block 618 (FIG. 6B), processing continues to block 600 (FIG. 6A).

In block 620 (FIG. 6C), the global correction engine 120 requests user information, including a user mark, from the local correction engine 160 a . . . 160 n of the local device 150 a . . . 150 n of the user. In block 622, the local correction engine 160 a . . . 160 n sends user information for the user who is associated with the user mark and with the local device. In various embodiments, the user information that is returned may be part of (i.e., the user information part) or all of the local device and user information 166 a . . . 166 n. In block 624, the global correction engine 120 stores the user information, including the user mark, in a data store. From block 624 (FIG. 6C), processing continues to block 604 (FIG. 6A). Thus, registration of the user occurs by the user providing a user mark used to control the local device 150 a . . . 150 n. In such embodiments, both the global correction engine 120 and the local correction engine 160 a . . . 160 n are able to detect user marks, and each of the local correction engines 160 a . . . 160 n is able to send a user mark to the global correction engine 120.

Coupling of the local device 150 a . . . 150 n with the global device 110 may be done in various ways. For example, in the case of a car's driver, no new logic is needed because modern cars already allow local devices 150 a . . . 150 n (e.g., smartphones) to register for several functions. This may also be true for airplanes in some cases, which allows use of the local device 150 a . . . 150 n for listening to airplane provided music. In addition, passengers or airplane touchscreen users may register when entering the vehicle or on the global touchscreen itself, by coupling the local device 150 a . . . 150 n through a Bluetooth code or other technologies.

In certain embodiments, the network delays of the communication from/to the local device 150 a . . . 150 n and the global device 110 may not be as fast as the instant applications of the two motions (of the vehicle and the user). With certain embodiments, it may be that the correction applied by the global correction engine 120 happens a short period of time after the error has been typed. However, with such embodiments, such near real-time correction suffices, as the error is corrected before the user notice the error or before the error has an effect on the next decision of the user.

In certain embodiments, the global correction engine 120 discovers how many local devices 150 a . . . 150 n (e.g., smartphones) are able to interact with the global touchscreen 122 and who is the user (e.g., owner) of each of the local devices 150 a . . . 150 n. Then, when the global touchscreen 122 receives input of a finger touch, the global correction engine 120 is able to associate the finger with the user and the local device 150 a . . . 150 n to apply the correction for that user (based on the local motion sensor information of the user's local device 150 a . . . 150 n).

In some embodiments, users actively register the local device 150 a . . . 150 n (e.g., smartphone) for a number of reasons (e.g., to download music, to make phone calls from a centralized system, etc.). In addition, the global correction engine 120 is able to detect whether the user and local device 150 a . . . 150 n have registered when the user touches the global touchscreen 122 with a user mark. If the user mark is not recognized (i.e., not found in the data store 140), the global correction engine 120 requests registration of that user.

In some embodiments, not all the touchscreens recognize the user mark and not all user marks are registered. In such embodiments, the user is asked to touch on a limited area of a touchscreen (global or local touchscreen) for registering a user mark. In certain embodiments, with multiple users using the same global touchscreen 122, the global correction engine 120 determines the correction based on the local device 150 a . . . 150 n associated with the last user who registered a user mark.

Also, in some embodiments, devices exist where all of the touchscreen is enabled for finger recognition. If the fingerprint touching the global touchscreen 122 is not recognized, the global correction engine 120 may still correct the location input using the last connected user (e.g., treating this as a good approximation) if such registration happened in a reasonable time window in the past.

In certain embodiments, the global correction system 120 performs correction in response to the user touching the global touchscreen 122 with a finger. Then, the global correction engine 120 searches for the fingerprint in the data store, and, if the fingerprint is not found, starts the registration of the user to obtain the fingerprint.

In other embodiments, the user provides a user mark (e.g., with a pen or other device used for input on the global touchscreen 122). Then, the global correction engine 120 searches for the user mark in the data store, and, if the fingerprint is not found, starts the registration of the user to obtain the user mark.

Then, at each time that the user touches the global touchscreen 122 with a finger, the global correction engine 120 obtains the relative motion of the local device 150 a . . . 150 n and applies a corrector factor to correct a location input of the finger on the global touchscreen 122.

In certain embodiments, the global correction engine 120 uses the following formula to determine an amount of change to the location input:

change in location input Δp=½αlocal device Δt ²

That is, the change in the location input (i.e., position) is equal to half of the acceleration (α) for the local device 150 a . . . 150 n times a unit of time for the user to act on the global touchscreen (Δt²). In certain embodiments, the unit of time is an estimated unit of time.

With embodiments, the local motion sensor 164 a . . . 164 n is able to provide both intensity and direction (latitude x, longitude y, and height z) of movement. In various embodiments, the global correction engine 120 takes into account one or more of latitude x, longitude y, and height z (e.g., certain embodiments may take latitude x into account). With embodiments, the global correction engine 120 estimates the change in location input as the time difference between the event of the acceleration registered by the local motion sensor 164 a . . . 164 n and the time the user pressed the global touchscreen 122, for very small amounts of time.

In the case of latency in the communication between the local device 150 a . . . 150 n and the global touchscreen 122, the correction may be applied with some delay, which works in various use cases, such as: switching a radio station, composing a phone number, looking up a contact in an address book, etc. In this case, the global correction engine 120 uses the following formula to determine an amount of change to the location input:

change in location input Δp=½(α_(local device)−α_(global touchscreen))Δt ²

That is, the change in the location input (i.e., position) is equal to half of the acceleration (α) for the local device 150 a . . . 150 n minus the acceleration (α) for the global touchscreen 122 times a unit of time for the user to act on the touchscreen (Δt²).

In certain embodiments, the unit of time is an estimated unit of time.

Embodiments calculate and mitigate the error in interacting with a global touchscreen 122 by using acceleration information coming from a local device 150 a . . . 150 n with a local motion sensor 164 a . . . 164 n associated to the user. In the case of multiple potential users of one single global touchscreen 122, embodiments identify which user is interacting with the global touchscreen 122 and select the correct source (local device 150 a . . . 150 n) of motion information in order to apply the correct fix to the location input to global touchscreen 122.

In certain embodiments, the motion is acceleration, and embodiments calculate relative acceleration and understand from which local device 150 a . . . 150 n of a plurality of local devices 150 a . . . 150 n that the other acceleration information is coming from. Embodiments link the user's own acceleration, via the local device 150 a . . . 150 n, with the acceleration of the vehicle 100.

Embodiments process location input of a user received from a touch sensor of a global touchscreen 122 of a global device 110.
